A statistical framework for quantitative spectroscopy of luminous blue stars
Miguel A. Urbaneja
Context: Quantitative spectroscopy of luminous blue stars relies on detailed non-LTE model atmospheres whose increasing physical realism makes direct, iterative analyses computatio…
The IACOB project: XVI. Surface helium abundances in Galactic O-type stars: indications for identifying binary interaction products
S. Simón-Díaz, G. Holgado, C. Martínez-Sebastián +13
The presence of massive O-type stars with surfaces enriched by CNO-cycle products has been known since the early 1980s. For many years, internal rotational mixing was assumed to be…
The IACOB project XIV. New clues on the location of the TAMS in the massive star domain
A. de Burgos, S. Simón-Díaz, M. A. Urbaneja +4
Massive stars play a very important role in many astrophysical fields. Yet, some fundamental aspects of their evolution remain poorly constrained. In this regard, there is an open…
Toward early-type eclipsing binaries as extragalactic milestones: IV. Physical properties of three detached O/B-type systems in the LMC
Mónica Taormina, G. Pietrzyński, R. -P. Kudritzki +10
We present a complete set of physical parameters for three early-type eclipsing binary systems in the Large Magellanic Cloud (LMC): OGLE LMC-ECL-17660, OGLE LMC-ECL-18794, and HV 2…
The IACOB project XI. No increase of mass-loss rates over the bistability region
Abel de Burgos, Zsolt Keszthelyi, Sergio Simón-Díaz +1
The properties of blue supergiants are key for constraining the end of the main sequence (MS) of massive stars. Whether the observed drop in the relative number of fast-rotating st…
The IACOB project X. Large-scale quantitative spectroscopic analysis of Galactic luminous blue stars
Abel de Burgos, Sergio Simón-Díaz, Miguel A. Urbaneja +1
Blue supergiants (BSGs) are key objects for understanding the evolution of massive stars. However, discrepancies between theoretical predictions and empirical observations have ope…
